Drop in water temp with A/C on

No experience with FD's, but on a stock FC this isn't too unusual if the ambient temps are not all that high (70's~80F ambient). Reason is on the FC T2's, we have a mechanical fan plus an auxilliary e-fan that kicks on whenever the A/C is turned on. So if you turn on the A/C, and it isn't all that hot outside, the aux. e-fan kicks on regardless pulling more cool air thru the rad. At those ambient temps, the the A/C isn't working all that hard to do much cooling (condensor doesn't get too hot), so the net effect of that extra airflow thru the radiator is lower water temps.

I know the FD uses an e-fan as its main fan, but does it have an aux. e-fan like the FC that comes on with the A/C?
